摘要: 为了解广西不同地区、不同生境福寿螺(Pomacea canaliculata)繁殖力大小及其影响因素,于2018年7–8月采集广西桂林市、来宾市、北海市3个地区6个生境(稻田、荒田、水沟、池塘、河流、沼泽)的福寿螺卵块,测量卵块长、宽、重量、卵粒总数和卵粒直径,并进行相关性分析。结果表明,广西夏季福寿螺单块卵粒数为48~1 041粒,均值为(256.19±155.67) 粒,其中池塘生境卵粒数最多,均值为(395.61±213.33)粒,荒田生境卵粒数最少,均值为(168.39±55.47)粒;卵粒直径为1.72~2.72 mm,均值为(2.17±0.17) mm,其中水沟生境卵粒直径最大,均值为(2.32±0.13) mm,稻田生境卵粒直径最小,均值为(2.07±0.16) mm;卵粒数和卵粒直径在不同地区均表现为来宾市>桂林市>北海市,卵粒数量在生境间表现为池塘>河流>沼泽>水沟>稻田>荒田,卵粒直径大小在生境间表现为池塘>沼泽>水沟>河流>荒田>稻田。夏季广西福寿螺繁殖力与纬度无关,离水面高度适宜繁殖或食物丰富的生境下福寿螺卵粒数较多、卵粒直径较大。在不同地区、生境间福寿螺卵粒数和卵粒直径有显著差异。

Abstract: In order to understand the reproductive capacity of Pomacea canaliculata in different regions of Guangxi and its influencing factors, six habitats (rice field, waste field, gutter, pond, river, swamp) in Guilin, Laibin and Beihai in Guangxi, were collected from July to August 2018. The length, width and weight of the eggs mass and egg diameter as well as the total number of eggs were measured. The correlations between incubation rate and these factors were analysed, respectively. The results showed that the number of single egg grains was 48~1 041, and the mean value was (256.19±155.67). The number of eggs in the pond habitat was the highest, and the mean value was (395.61±213.33). The number of eggs in waste field was the lowest, the mean value was (168.39±55.47); The egg diameter was 1.72~2.72 mm, mean value was (2.17±0.17) mm, and the diameter of the ditch habitat was the largest and the mean was (2.32±0.13) mm. The diameter of the egg in the rice field was the smallest, and the mean value was (2.07±0.16) mm. The number of egg grains and the diameter of egg grains in different areas were Laibin > Guilin > Beihai. The number of egg grains between habitats showed pond > river > swamp > ditch > paddy field > waste field. The diameter of the egg grains in the habitat was pond> swamp> ditch > river > waste field > rice field. Pomacea canaliculata in Guangxi in the summer was not related to latitude. The habitats with high water surface height or food were rich, and the number of eggs was larger and the diameter of the egg grains was larger. There were significant differences in egg number and egg diameter between different regions and habitats.
